Strikeglass vs. security film
Security film works after the glass breaks. Strikeglass is a clear shield bonded onto your existing windows and doors that keeps the glass from breaking in the first place. Unable to get in, and with the alarm going, most intruders give up and leave.
Strength and impact resistance
Strikeglass
- Up to 300× stronger than regular glass.
- Built to take repeated impacts from hammers, bats and crowbars without shattering.
Security film
- Adds shatter resistance, but the glass still breaks.
- The film holds the shards together and slows entry, but does not stop it. Once the edges give, the whole pane can be pushed or kicked in.
Verdict: Strikeglass prevents entry. Security film only delays it.
Installation
Strikeglass
- A clear shield bonded onto your existing glass. No window replacement.
- Can be framed to fit cleanly on commercial or residential windows and doors.
Security film
- Stuck directly onto the inside surface of the existing glass.
- Weak at the edges unless it is installed with a special retention system, such as anchoring caulk.
Verdict: Strikeglass is the more secure, tamper-resistant installation.
Appearance over time
Strikeglass
- Optical-grade sheets that are very clear and nearly invisible.
- Anti-scratch coatings help keep it that way.
Security film
- Also clear at first, but it can fade or bubble over time, especially cheaper films.
Verdict: Strikeglass holds up better to sun and weather over the years.
UV protection and insulation
Strikeglass
- Offers UV protection.
- Adds a layer of insulation to your existing windows, and can be combined with Low-E coatings or used as part of a hybrid sealed unit.
Security film
- Can offer UV protection.
- Adds very little insulation.
Verdict: Strikeglass adds insulation that film does not.

For serious protection against break-ins, looting or vandalism, Strikeglass is the stronger choice. Film can be a low-cost supplement, but it is not a barrier on its own.
